2. Related Art

Generally, color paints are usually applied to coat on surfaces of objects, such as cement wall, plastic, and metal, so that they can have different colors. In order to allow the color of the color paint to be adhered onto the surface of the object, some resins, such as acrylic resin, amino resin, are usually added to the color paint during formulation, thus the color paint will satisfy the requirements of physical and chemical properties.

The color paint contains a colored paste, powder fillers, such as calcium carbonate, talc powder and pearl powder, an additive, a solvent, and the resin described above. The colored paste is produced by mixing the toner powder with the resin special for toner powder (may be a saturated polyester resin) and grinding to some degree of fineness. The saturated polyester resin special for toner powder is compatible with other resins, thus being capable of being used with various resins together.

However, when the saturated polyester resin special for toner powder is mixed with other resins, the physical properties and the chemical properties, such as adhesion, bending, impact resistance, weather resistance, salt spray resistance, vary with the mixing ratio. Therefore, how to solve such a problem is a common objective in the industry.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a color paint formula adjusting system and method thereof. A color paint 20 formula adjusting system 30 of the present invention is used to adjust the color paint 20 formula for different paint systems 10 and the objects to be used, for example, metal, plastic, wood, and so on. Each main paint system 10 includes the following setting regions, as showed in FIG. 1:

(A) a PU paint system setting region 110: formed by reacting resins containing polyols, such as alkyd resin, acrylic resin, and saturated polyester resin, with polyisocyanate containing NCO.

(B) a baking coating system setting region 120: a baking coating system formed by reacting the resins, such as alkyd resin, acrylic resin, and saturated polyester resin, with amino resin at high temperature.

(C) an epoxy paint system setting region 130: a paint system formed by reacting epoxy resin with amino resin or reacting epoxy resin with polyamide resin.

(D) a nitro cello solve paint system setting region 140: a paint system formed by mixing the resin with nitro cello solve; and

(E) a thermoplastic acrylic resin paint system setting region 150.

As the formulation of the color paint 20, different paint system 10 will produce different physical and chemical properties due to different formula ratios, even if the contents are the same. FIG. 2 is a schematic view of compositions of a color paint 20. In general, taking the baking coating system as an example, the color paint 20 includes a toner powder 210 of many different colors, a powder filler 220, a saturated polyester resin solid content 230, an acrylic resin solid content 240, and an amino resin solid content 250. Colored pastes can be formed by the toner powder 210 and the saturated polyester resin solid content 230 in different ratios. The powder filler 220 makes the color paint 20 to display different colors and luster, or different surface smoothness and effects, for example, the addition of a pearl powder makes the painted surface to display pearly luster. The powder filler 220 can also affect the physical and chemical properties of the color paint 20, and the powder fillers 220 may interact with one another in the color paint 20. The solid content is the percentage of the solute (non-volatile matter) per unit weight, that is:

${{solid}\mspace{14mu} {content}} = {\frac{solute}{\left( {{solute} + {solvent}} \right)} \times 100\%}$

For different objects of the color paint 20, desired physical and chemical properties suitable for the objects are required to be found out, while the mix ratios of the physical and chemical properties are necessary to be obtained through pre-experiments. The data of the color paint 20 formulas are recorded and stored in a database 310 according to the restrictive conditions of the paint system 10 and the requirements of physical and chemical properties corresponding to the objects and the mix ratio of the color paint 20 formula in the paint system 10, so as to be used as a basis for adjustment. The database 310 may be various storage media stored in the local port, such as a hard disk (HD), a compact disc (CD). The database 310 is a relational database and includes the restrictive conditions and the proportion of the contents in each paint system 10 and the relationship between the contents.

Therefore, FIG. 3 is an architectural view of a color paint formula adjusting system 30 of the present invention. Referring to FIG. 3, the color paint formula adjusting system 30 includes a database 310, an acquiring module 320, a computing module 330, a query module 340, a comparing module 350, a statistic module 360, and a network module 370. The execution of the system can be realized on a single computer, or through a network server. The user can log onto the server for providing the color paint formula adjusting system 30 from the computer terminal through a wired or wireless network. When receiving a log-on request of the user, the network module 370 authenticates the account and password input by a user. After authentication is passed, the user can select and set the paint system 10 and the object, as showed in FIG. 1.

After selecting and setting are completed, as showed in FIGS. 4 a and 5 a, “product number”, “product name”, and “ratio” for being used in the selected paint system are displayed on the display screen for the user, as well as “price” of every product as a reference to the user. Then, after the user clicks a “Calculating conversion rate” icon 420, the proportions are input in the “proportion field” of each formula to be added and the total amount to be formulated and the units thereof are also input. FIG. 6 is a flow diagram of the method of the present invention. Referring to FIG. 6, first, the amounts and units of each of the color paint 20 formula input by the user in the display are received by the acquiring module 320 (step 610). For example, in FIG. 4 a, “85 ” is input in the proportion field of a baking A resin (AR), “100” is input in the proportion field of a baking B resin (BS).

Next, the query module 340 calculates the resin and total resin solid content contained in each of the colored paste, that is, according to the colored paint 20 formula selected by the user, the data of the formula, for example, the individual proportion of toner powder 210 and saturated polyester resin solid content 230 contained in the jet black colored paste, is queried from the database 310, so as to calculate their amounts in the colored paste input by the user respectively (step 620). Since the color is determined by the amounts of the toner powder 210 and powder filler, the hue will not be changed by adjusting other resins when the amounts of the toner powder 210 and powder filler are kept constant. However, the resins will affect the physical and chemical properties, that is, the proportions of the saturated polyester resin solid content 230, the acrylic resin solid content 240, and the amino resin solid content 250 must be restricted in a certain proportions. Furthermore, the interaction between the powder fillers 220 will affect the change of the physical and chemical properties of the color paint 20 to be formulated.

With a fixed colored paste and powder filler proportion, the theory value of the desired total resin solid content is calculated according to the restrictive conditions, that is, in addition to the data in each colored paste, the query module 340 queries the restrictive conditions of the compositions of the color paint 20, i.e. (f1) to (f6), as showed in FIG. 7, in which D1 to D6 are limit values obtained through experiments. When the theory value of the total resin solid content input by the user is calculated (step 630), the statistic module 360 calculates the statistic values, such as the amounts of the total resin solid content special for toner powder 210, the amount of each powder filler 220, the total amount of the powder fillers 220 interacting with one another, the amount of the total toner powder 210, the amount of the total powder fillers 220, the total amount of the total toner powder 210 and total powder fillers 220, and so on and the values of ratio to the total resin solid content, as well as the ratio values of the amounts to the total resin solid content, and the comparing module 350 determines whether each ratio value is less than or equal to the limit value.

If not all of the ratio values calculated by the statistic module 360 is less than or equal to the limit value, the total resin solid content proportion must be adjusted (increased) appropriately. If none of the restrictive conditions in (f1) to (f6) is satisfied, an optimal mix ratio of the formulation of the paint resins is read according to the data input by the user, that is, the mix ratios of the acrylic resin solid content 240 and the amino resin solid content 250 recorded in the database 310 are increased. The computing module 330 calculates an adjustment values which satisfy the limiting conditions with minimal increase of the two mix ratios, to get the optimal mix ratios (step 640). The desired adding amounts of each formula of the user are obtained according to the formula ratios. As showed in FIGS. 4 b and 5 b, after being adjusted by the system of the present invention, the “proportion field” shows the total amount is 100 kg (as showed in FIG. 4 b), and at this time, the total resin solid content input by the user or the theory value thereof is estimated assign proportions of the resins to be added (step 650).

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
